Preheat your oven to 350°F (175°C). Line a 12-cup muffin tin with aluminum cupcake liners and give them a light spray with cooking oil.
For the Cookie Dough:
1. In a food processor, combine the cold butter, almond flour, and granular sweetener. Pulse briefly until the mixture resembles coarse crumbs.
2. Add the egg, softened cream cheese, molasses (if using), baking soda, and vanilla extract to the food processor. Process until a smooth dough ball forms, scraping down the sides as needed.
3. Gently fold in the 2/3 cup sugar-free chocolate chips into the dough by hand.
4. Divide the dough evenly among the 12 prepared muffin cups.
5. Bake for 13-15 minutes, or until the edges are golden brown.
6. Let the cookie cups cool in the tin for 5 minutes. Then, using a tart tamper or the back of a spoon, press gently into the center of each cookie to create a well. Allow them to cool completely.
For the Ganache Filling:
1. In a small microwave-safe bowl or saucepan, heat the heavy cream until it just starts to bubble around the edges (about 1 minute in the microwave). Do not let it boil vigorously.
2. Add the 4 ounces of sugar-free chocolate chips and the powdered sweetener to the hot cream. Stir continuously until the chocolate is fully melted and the ganache is smooth and glossy.
3. For an extra silky-smooth ganache, blend it briefly with a stick blender if you have one.
To Assemble:
1. Pour the warm ganache filling into the wells of the cooled cookie cups.
2. Let the ganache set slightly before serving for a firmer filling.
